Researchers at the University of California, Davis have developed a method for producing aligned, food-grade hydrogel fibers at high throughput for scalable cultivated meat manufacturing.

Medium Access Control (MAC) protocols determine how multiple devices share a single communication channel. This started with Additive Links On-Line Hawaii Area (ALOHA) channel protocol and advanced to Carrier Sense Multiple Access (CSMA) protocols, variants of which are used today as WiFi standards. Such random access protocols are generally divided into contention-based methods like ALOHA and CSMA which are simple yet can have collisions at high traffic loads, and contention-free methods like Time Division Multiple Access (TDMA) which offer high efficiency but require complex clock synchronization and inflexible time slotting. While distributed queuing concepts have been pitched to help bridge this gap (e.g., DQDB or DQRAP) they have traditionally relied on physical time slots, dual buses, and/or complex signaling that makes them less suitable for the modern demands of wireless networks.

Professor Jin Nam and colleagues from the University of California, Riverside have developed novel synthesize piezoelectric scaffolds that can be remotely activated without a physically connected electrical wire to produce optimal electric fields in vivo for enhanced nerve regeneration. The technology works by using a biocompatible nanofibrous scaffold with a mesh-like structure that mimics the body’s natural tissue architecture and is made from piezoelectric materials. This technology allows for the mechano-electrical stimulation (MES) on endogenous or transplanted stem cells to enhance their neural differentiation/maturation. This technology is advantageous because this scaffold can be applied as a conduit or patch and activated remotely and non-invasively.  Fig 1: In vivo characterization of piezoelectric conduits and their impact on sciatic nerve regeneration.
